perf/x86: Unregister PMI handler on PMU init failure
Fix an NMI handler leak in init_hw_perf_events(). When PMU
initialization fails after register_nmi_handler(), the error path
exits without calling unregister_nmi_handler(), leaving a stale
NMI_LOCAL "PMI" handler registered. Add the missing call before
clearing x86_pmu state.
